First of all, you should correct your point of view. Although speaking Mandarin is advocated by the state, it does not mean that Mandarin is superior. It is only a language used to facilitate the communication between people of all ethnic groups, and it is not the first of all languages. Secondly, do as the Romans do, ok? Cantonese people have spoken their own language in their hometown for generations. As long as you are a foreigner, people will change with you. It doesn't make any sense. Learn if you don't understand. Is it necessary for foreigners to learn Mandarin when studying abroad? Someone downstairs actually said that Cantonese people are local ruffians. Which province has no local ruffians? Obviously, it is their own waywardness. I still think that the fault of Cantonese people is that you are wrong. I am a native of Guangzhou, and there are many classmates around me who used to speak Mandarin, but they have never been like you. In recent years, most of my classmates can speak Cantonese, even if they can't, they will listen. The key is whether you have a heart to learn. When you go to other people's homes, others have to obey your rules. This is too strange ... Finally, I hope you can learn Cantonese well. After all, learning another language won't do you any harm.
